ln(7x-12)=2ln(x)

ln (7 x - 12) = 2 ln (x)

x = 4, x = 3

Solution steps

ln (7 x - 12) = 2 ln (x)

Apply log rules

7 x - 12 = x^{2}

Solve

7 x - 12 = x^{2} : x = 4, x = 3

x = 4, x = 3

Verify Solutions:

x = 4

True

, x = 3

True

The solutions are

x = 4, x = 3

lo g_{b} (1000) = 3

0.912 = ln (x^{2})

lo g_{a} (2048) = 11

ln (3) + ln (2 x + 5) = 2 ln (x + 2)

lo g_{20} (x) = 1 + lo g_{20} (10)
